Expansion of XX Hotel Group

Grace Shaanxi Energy Saving and Environmental Protection Co., Ltd. Plan

Good hotel energy-saving service plan

First of all, the current electricity situation of the hotel

Sec. With the rapid development of the three industries, as a typical power service industry, the number of industries is increasing rapidly and competition is becoming more and more popular. Most hotels and other businesses are facing declining profits. The electrical equipment within the hotel is in order to provide guests with a comfortable environment. Each room not only has photoelectric lights, TVs, refrigerators, air conditioners, water heaters, water heaters and other electrical equipment, if they are all open, all the power exceeds 2000 watts. , which means that if a traveler is in the room and all appliances are turned on, the amount of power required by an hour exceeds 2 degrees.

A common indicator in international hotels and other industries, the day's power assigned to each room is 23 to 26 degrees. This is a hotel with 1,000 customers, which consumes about 23,000 to 26,000 industrial electricity costs every day. The cost of electricity is a major cost control cost. Electricity costs have become necessary for hotels, but they are also the most effective means of reducing hotel operating costs. Improve the competitiveness of the industry.

Analysis of power symptoms of hotels

(1) Severe energy loss in transmission and distribution systems

1. Due to seasonal or peak tourist season, The usage efficiency of the power grid is not high

When the hotel occupancy rate changes greatly, the load rate of the transformer is generally not high, and sometimes it operates with almost no load, resulting in large losses of the transformer itself and high voltage change rate, which is unnecessary waste .

The power supply line has large losses

Due to the long transmission distance, apparent power, and multi-branch power lines of the hotel’s electrical equipment, a large amount of losses are concentrated and the influence of thermal resistance line losses is , leading to a decrease in terminal voltage, a decrease in energy efficiency, and certain safety hazards;

3. Poor power quality, the number and type of large electrical equipment in hotels, power electronic devices, electrical appliances, and non-linear loads The use of electric power leads to severe load nonlinearity, voltage waveform distortion, and poor power quality, which greatly reduces energy efficiency and also affects the service life and safety of electrical equipment.

(B) The utilization rate of energy consumed by electrical equipment is not high

Room mixed load line power guest room electrical load lighting, television, water heaters and other water machines.

, most lighting equipment or old-fashioned incandescent lamps, energy consumption;

b, all electrical equipment with single-phase power supply, is a serious three-phase unbalanced line, This results in excessive zero sequence current and increased energy loss.

C. The working voltage is generally higher than the rated value, which not only allows more efficient lighting, water diversion, water heaters and other equipment, but will also cause equipment to heat up and fail prematurely, wasting energy and reducing electrical life. equipment.

2. Air conditioning equipment (cabinet or central air conditioning) First of all, the design of the hotel air conditioning system is selected. Most of them are expected to maintain a margin of about 20%, but due to the impact of the room occupancy rate,

Rarely run completely at full load; second, the air-conditioning circulating water system actually runs at a fixed maximum design flow rate, does not change with the load, and cannot reach the comfortable temperature of the host, auxiliary equipment and third Reasonable dynamic automatic adjustment ends, and the generated power utilization rate is low, which is a serious waste of energy.

(3) Guests’ energy-saving awareness, simple energy-saving management

Hotel profit business, facing customer base, temporary accommodation for foreign countries, money everywhere, and There is no need to enjoy the consumer psychology, coupled with the timely monitoring of the fate of hotel rooms and power consumption, it is because there are always bright lights during the day, and phenomena such as forgetting to turn off the lights, TVs and other electrical equipment when going out lead to very serious energy consumption waste. At the same time, most hotels manage lean management of overall energy use from the perspective of guest needs, but from the perspective of electricity consumption that supports the normal operation of equipment, rather than from the perspective of usage efficiency, energy consumption standards and equipment service life. Energy utilization rate is low.

The hotel saves the system

(1), project design
